If you are making world or release twice from one source, you will get some binaries and lot of libraries which differ because of time stamps: # make buildworld # make installworld DESTDIR=/home/build1 # rm -r /usr/obj/usr # make buildworld # make installworld DESTDIR=/home/build2 # diff -r /home/build1 /home/build2 freebsd-update-server also make world twice to find out where those build stamps are. I tried to freeze clock on build box while repeating build process: # while true; do date -n 0000; sleep 0.5; done and there were no differences between two builds. Is there any harm if I build releases with frozen clock? or maybe load kld module which replace gettimeofday syscall at build time? thanks, Artis
